Intro I first wrote about the P-38 in Torrey Pines back in mid-2020. It is a well known wreck that was discovered a number of years ago and has been deteriorating due to multiple factors. After our dive on the deeper P-38 in Solana Beach, we were headed to this wreck. Since I started building [...]
I am very honored to be awarded the Winner in the Wreck Category for the 2023 Underwater Photographer of the Year (UPY) contest. The "photo" that won is a screen capture of the final photogrammetry model I built of the F8F-1 Bearcat that sits 230 feet deep off Point Loma, California. To date, there have [...]
Background I held my first photogrammetry class between Friday, Jan 20th through Sunday, Jan 22nd. This the first time I held the workshop and the results were very good given the conditions we had for the dive day on Saturday, Jan 21st. After a day of lecture and building a model on land, we dove [...]
I recently gave a presentation on the Zoom Seekers series. It was focussed on Southern California Wrecks and coves some of the tools we use to find and identify new wrecks. It provides details on how photogrammetry can be used for multiple purposes in wreck identification. I hope this presentation provides a peek into what [...]
Intro I published a Top 10 Diving Recap in 2020 and then again in 2021. This year I am making it a "Top 10 Dives and Projects" list since quite a bit of my diving this year has been working on more longer-term projects that involve multiple dives on the same wreck. It has been [...]
Background The Ruby E was the second vessel intentionally sunk off of Mission Beach, San Diego as part of "wreck alley." She was built in 1934 and sank on June 18, 1989 so she has been down for a while. This post will give some history of the ship, pictures from a recent dive, and [...]
I have almost the entire photogrammetry model of the Yukon complete -- in fact, I had it almost complete after dive 5. However, I'm still facing the ongoing problem with the moving seaweed and not being able to align photos for the starboard side hull. Below is the "state of the project" after the "Seaweed [...]
I have quite a few local wreck photogrammetry projects lined up for the end of 2022 and well into 2023. Here is a teaser for one that I started working on after a recent dive. For those who don't recognize this wreck, it is split in two pieces that are separated by quite some distance [...]
Intro / Background This will be a relatively quick post since I did the dive on Dec 2nd and have since done Dive #7 but I wanted to provide a chronological update on my "battle" to build a photogrammetry model of the Yukon. After Dive #5 (The "Butterfly Effect"), I had most of the wreck [...]
I have decided to offer a three-day Photogrammetry Workshop. If there is enough demand, I will offer it multiple times during 2023. During the workshop, students will learn to take photos for a model and will build multiple models (both land based and under water) using Metashape software. The goal of the workshop is for [...]
